Hydraulics

Rugged Dependability

John Henry Foster is a leading carrier of hydraulic cylinders, pumps, hydraulic valves, couplings, hoses and more. With ready-to-ship components and application expertise, we either have what you need in our inventory or we’ll custom design it for you.

Accumulators

Hydraulic accumulators regulate the performance of a hydraulic system by providing an additional volume of system fluid, pressurized by an external gas supply. JHF offers three types of accumulators for industrial applications: piston, bladder and diaphragm.

Couplers

Cylinders

Hydraulic cylinders transfer energy to power different applications in a hydraulic system. Hydraulic cylinders consist of a piston and a rod, which are powered by pressurized fluid. Choose from a large selection of rugged, dependable hydraulic cylinders for any application. We have a wide variety of both standard and specialty styles and sizes to help you get the job done.

Filters

Hydraulic filtration and accessories maintain valves, pumps, and motors in hydraulic systems. Filters remove contaminants in hydraulic fluid. For any job, we have a variety of low to high pressure filters and a large selection of filter accessories to keep your next project moving.

Gauges

Without gauges, fluid power systems would be both unpredictable and unreliable. Our gauges can be ordered with a variety of accuracies, fluid compositions, temperatures, pressure ranges and mounting methods. Make sure there are no leaks or pressure changes with a wide variety of hydraulic gauges- for any environment- from John Henry Foster Company.

Hydraulic Leak Testing & Calibration

John Henry Foster Company is your place for leak and pressure testing connectors. Improve manufacturing costs and efficiencies with quick, temporary connections to seal a wide-variety of tubes, holes, thread profiles and test-piece features.

Motors and Power Units

Choose from a large selection of standard, out-of-the-box products, or work with our engineers to customize a component of system specifically designed to meet your specification. Any size, any quantity, any application. Ensure efficiency, safety and durability with JHF hydraulic systems and components.

Pumps

Hydraulic pumps use a variety of methods, such as gears or vanes, to pressurize fluid and transfer it into hydraulic systems. Accessory and replacement parts are used to maintain pumps and repair worn parts. With a wide variety of piston, electric, gear, vane pumps and more, we have the hydraulic pumps and accessories your operation requires.

Shock Absorbers

Hydraulic shock absorbers and vibration isolators control shock and vibration in hydraulic systems. Shock absorbers absorb, convert, recycle, and dissipate energy. Also called dampers or dashpots, they are used with springs and cushions to absorb shock and prevent damage to equipment. They are used in automotive suspensions, airplane landing gear, and industrial machinery. Vibration isolators reduce noise and vibration caused by machines. They prevent damage to equipment and protect workers from loud, constant noise.
